This demo shows how to filter data in the List using the FilterBuilder widget. Here, the FilterBuilder provides a set of built-in filter operations, as well as a custom "anyof" operation which is implemented in the customOperations array. A condition with this operation evaluates to true if the data field contains any value from the list. Note that the calculateFilterExpression function converts the «anyof» operation into a set of operations supported by the DataSource. This operation is available only for the "Category" field because it is specified in the field’s filterOperations array.
